Thul Hairo Khan

Thul Hairo Khan is a Buddhist stupa built between the 5th and 7th centuries CE near Johi in Sindh, Pakistan[1]. The structure measures 15 metres (50 ft) in height and 9 metres (30 ft) in width, constructed using cheroli and mud mortar to combine mud bricks and baked bricks[1]. Notable features include stairs on the north side leading to the top and an arched tunnel running from north to south at ground level[1].
